[Boot Problem] Windows 8 boot entry black screen.

So, I own an old Pentium 4 machine, which doesn't support NX bit. I really want to install Windows 8 on this machine, and I found @Jan1's CPU feature patch. Everything went fine, until I actually tried to boot into extracted installation from install.wim. Through EasyBCD I've added Windows 8 entry to bootloader, but, when I choose the entry, or press F8, screen just goes black and nothing happens. it can sit like that for hours. Maybe someone knows, what's the problem with it?
